Must admit, I mute everyone that uses the little sound effects, in PvP. (Maybe they implemented an option since then, but a few months back, there wasn’t an option to just disable those sounds, in PvP (only), so… Instead, muting people does the trick. I don’t personally see the need to not even display that they talked, since people might answer them and it would make it hard, for me, to follow the conversation, but if it’s easier for some to enjoy the game that way, sounds like a nice option to have.
